I know of a lot of people who get upset about the salvation message concerning people on their deathbed. This is especially true with criminals, rapists, and others who some feel led a life that doesn't truly seek salvation. I think that none of us are able to judge a person's heart. That's God's job. It might not seem fair to some people but what if they got rejected from salvation for their sins. Nobody would be saved! I think we should count it a blessing every time someone comes to Christ, even if their doing it at the last minute. We should be especially joyful if these "bad people" are truly repentant.
